Besides Raghunath, the selectors also ignored the experienced Danish Mujtaba and Devinder Walmiki both of whom were part of the Rio Olympics squad.
The probables selected by chief coach Roelant Oltmans along with HI selectors did not feature right back Gurbaj Singh.
Gurbaj, who was the most expensive player in the last Hockey India League bid, continued to get the boot.
Although HI did not give a reason for Raghunath's omission, sources hinted that the strongly built drag-flicker had requested for a break after playing continuously for the past few years.

The national camp will commence at the Sports Authority of India in Bengaluru from March 14.
The list includes as many as 11 players from last year's gold medal junior World Cup winning squad.

While Mandeep Singh, Harjeet Singh, Harmanpreet Singh and Vikas Dahiya have been part of the senior men's camp earlier, defenders Dipsan Tirkey and Gurinder Singh, midfielders Sumit, Nilakanta Sharma, Manpreet and Simranjeet Singh, forward Gurjant Singh are the latest inclusions in the core group, which will be put through the grind ahead of the Sultan Azlan Shah Cup in April, followed by the Men's Hockey World League Semi-Final London 2017 in June.

"It was a busy start to the new year with the HIL, where I feel some of the players did extremely well under pressure situations. Like I had mentioned earlier, the selection process for the core probables was based on the players' performances in the year 2016 as well as the 2017 HIL. This is an important year for Indian hockey with the Men's Hockey World League Semi-Final London 2017 and the World League Final in December," said Oltmans.
The 62-year-old Dutchman will be joined by new recruits Hans Streeder, who has replaced Roger van Gent as the analytical coach for the senior men's team, and Scott Conway, who has been brought in as the new scientific advisor.
While Streeder was earlier with the junior men's Dutch squad and has been in the coaching profession since 1983, Conway from Australia has been practicing sports science since 2011 and was previously with the Institute of Sukan Negara & Malaysian Hockey Confederation.
